To all 1117mm it nmg concern.-

Be it known that I, .Licon SMITH J ARMANN, a subject of the King ofNorway, residing at Ghristiania, Norway, have invented new and usefulImprovements in Breech-Loading Fire- Arms and in Repeating MagazinesTherefor, of which the following is a specification.

Fire-arms constructed according to this invention have a breech partwhich consists of the breech-case and of the following six parts, whichare movable thereinviz., the breech bolt, the closing and thrust block,the hammer, the extractor, the striker, and the mainspring. Thismechanism is applied to a gun which is provided with acartridge-magazine in the upper part of the gun and a cartridge magazineunder-the barrel, the whole arrangement being such that the gun may besupplied first from one magazine and then from the other magazine 5 orthe gun may be made with the upper magazine alone or with the lowermagazine alone. The breech mechanism remains substantially the same inall the afore said eases.

The breech-case A, Figs. 1 and 2, whiclris screwed to the barrel,consists of a cylindrical tube, as usual in the bolt system, inside ofwhich the movable breech mechanism works during the manipulation of thegun. The breech-case, as described below, and also the details of thebreech mechanism and its arrangements, differ essentially from oldertypes in Belgium January 15,1833, No. ',ItiI,'and in Germany of thissystem. Thus the thrust or recoil is taken up by a slot, (6 whichreceives the lever of the closing-block 0, Figs. 7 and 8, and by agroove, a, which receives the thrust-knob of the closing-block, so thatthe thrust or recoil is taken up diametrically on both sides of thebreech-case, which, as regards solidity and accuracy in firing, hasconsiderable advantages. For the downward movement of the lever of theclosing-block, a curved inclined plane, a a, in the aforesaid slot acauses the cartridge to be pressed into the cartridgechamber, and in thereverse movement of the lever a curved inclined plane, a a in theaforesaid groove a causes an effective extraction of the cartridge-case.Thereby the thrust 7 knob C of the closing-block 0, Figs. 7 and 8,

is forced over this curve. A slot, a, receives the knob d of the hammerD, Figs. 9 and 10, that has the full and half cock notches d and d andthe third knob, 0 of the closing-block O, and it'serves, also, forguiding the movable breech mechanism in its forward and backward motionduring the manipulation of the gun. A notch, a, at the rear serves as asupport for the projection h, Figs. and 16, for the trigger-spring. Amortise, a receives the cocking-knoblrof the trigger-spring. A lowerlug, a", Figs. 1, 32, and 33, serves for fastening the breech mechanismto the stock, and by its lateral projections to on the said lug thespring of the cartridge-feeder for the magazine under the barrel issecured, as will be described later on with reference to the magazineunder the barrel. There is also a knob, a, at the rear for fastening themechanism to the stock. The upper stop-notches, a a, stop the movablebreech mechanism from moving backward farther than till theextractor-head abuts against these notches. A recess, a, in the socketfor the barrel receives the extractorhook 0, Figs. 11 and 12, when themechanism is closed.

The special arrangements of the breechcase where the magazine K is to bemade detachable are as follows: On the right side of the breech casethere is a recess, a, into which is inserted the stud of the loosemagazine. Near the top and more to the rear there is a recess, (0,f0rmounting the magazine. A screw-hole, a, is provided on the bottom of thebreech-case for an ejecting-pin, which is only necessary when the loosemagazine is intended to be used.

The movable breech mechanism consists of the following parts: Thebreech-bolt B, Figs. 14:, 15, 50, and 62, is a cylinder with a frontend, I), having a hole for the striker F. In the interior of thiscylinder the mainspring and the striker are generally placed, the latterbeing in this case guided in a lateral groove, 1)". The bolt has alug,b, at the rear, by which the closingblock draws the bolt back. On

1 top a circular cut, 1), opens laterally and secures the end eofextractor E, Fig. 11. A

recess, Z1 receives the knob e on the front end of the extractor. Thebolt B has a fiat face, N, to permit it to pass over the ejectingknob a,in the bottom of the breech-case.

The closing and thrust block 0, Figs. 7 and 8, is formed with a pivot,c, that fits in the hollow cylinder 1) of the bolt, and there is a hole,0, for the striker F, Figs. 13 and 14.. On this pivot the closing-block0 turns sufficiently for opening or closing the mechanism. Theclosing-block is provided with the lever-knob 0 by which the mechanismis worked during the manipulation of the gun, and when the mechanism isclosed this lever takes up the thrust in the aforesaid slot (6 of thebreeclr case simultaneously with a lower thrust-knob, c, that takes upthe thrust in the aforesaid groove a in the breech-case. Further, theclosing-block is provided with a projection, 0 that engages with therearlug or stud, b of the bolt B, Fig. 1a. YVhen the lever is turned up,therefore, in drawing the mechanism backward, the bolt is carried alongby a spirallyformed incline plane, 0". at the back. The gun, as usual inthe bolt system, is cocked when the closing -block is thrown up. Acurved covering-plate, c. on the closing-block protects the mechanismagainst dirt and imparts by its forward edge and rounded corner 0 aforward impulse to the sliding carrier in the magazine. This curvedplate also looks this magazine when the mechanism is closed and keepsitfirm during firing.

The hammer D, Figs. 9 and 10', has a spirally-formed inclined plane, d,corresponding with the inclined plane c of the closing-block, as shownby dotted lines. Through the middle of the hammer is a hole, d, partlyscrewthreaded, for connecting the striker F to said hammer. The hammeris provided underneath with a knob, d", with a nose, (1, for fullcockand a notch, (1*, for half-cock. This knob is guided in the slot a inthe rear end of the breech-case A, Figs. 1, 2, and 33. There is also afront projection, (P, which also serves for guiding the hammer in thebreech-case. By the comb d the gun may be full or also half cocked. Thepoint of the spirallyformed inclined plane a in the closing-block C,Fig. 7, rests in a recess, d formed in front end of cock, and thisprevents the hammer from turningwhen the mechanism is opened.

The extractor E, Figs. 11 and 12, consists of a very powerful spring, 0,provided. with a round button-formed knob, e, by which it is fastened tothe thrust-bolt B at b, and when in this position the extractor isturned till ,7

a knob, 0 at the front enters the recess b at front end of the bolt B,when the extractor is secured and in its right position. To take out theextractor only requires the lifting of the knob e out of the out If inthe bolt and the turning of the extractor a quarter-circle to eitherside. The fore part of the extractor E isprovided with a head, 6', eachprojecting side of which, when the breech mechanism is open, abutsagainst the stop-notches a a in the breech-case, and thus arrests thebackward movement of the mechanism. a" is the ex ti'actingclaw. Theextractor-head c is also, at the right side, provided with a lug, 0",Fig. 12, that gives motion to the repeating mechanism of theloosemagazine K, Fig. 19. Bylifting up the extracting-claw (2 (usin forinstance, the right forefinger for that purpose) sufficient to allow thetwo side projections of the extractor-head c to slide over thestrengthened part of the breecltcase, (at the aforesaid thrust-slot(62,) the movable breech mechanism may be removed from the breech. Bypushing the mechanism forward it may be again refitted, theextractorspring thereby beinglifted up and sliding freely up theinclined plane on the rear of the breech-case until the extractor-head chas passed the above-named strengthened part of the breech-case,whereupon the extractor-head 6" again drops down into the stop-notches aa", and the mechanism is then in the position shown in Fig. 50. Thisextractor has thus the following functions to perform, viz.:

First. To extract the cartridge-case from the chamber as usual--viz., bythe hook 0*.

Second. To eject the empty case. This is done only through the tensionof the (3X- tractor-spring, which presses the rim or flange of thecartridgecase so hard against the bot tom of the breech-case that thefriction thereby produced is sufficient to throw the empty case gentlyclear of the gun.

Third. To stop the travel of the movable mechanism.

Fourth. To assistin removing the movable breech mechanism from the case.

Fifth. To secure the movable breech mechanisin.

Sixth. To guide the back and forward movements of the bolt.

Seventh. iVhen using the loose magazine K it serves also for givingpartial impulse to the repeating mechanism of this magazine.

The striker F has at the front end a head, f, that fits in theinnercylinder, 7), of the bolt B. In instances where a cartridge bursts, thehead has to let the gas escape, and for this purpose the head is formedwith grooves 0r hollows, f, by which the violent repulse of the pistonis partially prevented. Near the middle the striker has a shoulder, fwhich in such cases is forced into contact with the pivot c of theclosing-block, Fig. 8, and thereby prevents any flow of gas toward theeye of the operator and keeps the mainspring from being over-forced. Toprevent the striker from unscrewing itselfthe headf" provided with afeather, f, that moves in the cone spending groove, Zr, in the bolt. Theback end of the striker has screw-threads f, which are for screwing itinto the hammer. The main spring 0 is, as usual in this system, ahelical steel spring.

The trigger mechanism consists of- First. The tri gger'sprln g H, Figs.15 and 16, which is placed beneath the breech-case,at the rear of thesame, between the notches of and a provided therein, and has a hook, it,that catches in the back notch, (17, in the breechcase A, whereby thespring H, fastened by a screw, is protected against the shock caused bythe forward movement of the breech mechanism. The spring has a slot, 71for the trigger J, which is hinged thereto by a pin, 71?. On the upperside, at the foremost end, this spring has the cocking stop-lug it, thatenters the opening a in the breech-case, where itiirst meets with thefull-cocking notch d of the hammer D.

Second. The trigger J, Figs. 17 and 18, has a rounded projection on thetop a, which abuts against the breech-case, and by which most of thepulling is done. \Vhen this first touch is felt the rest of the pullingrequires a con tinual and but very slight pressure on the trigger.

The following is a description of the next part of my invention, whichrefers to the re peating detachable magazine K, Figs. 19 and 56 to 60.This is mounted on the top of the gun, standing out at an angle andcommunieating directly with the breech. Though preferably detachable, itmay, if desired, be permanently fixed. 7

The magazine K consists ofa lower case, 7;, for the mechanism. To thiscase is soldered the cartridge-holder 7.", inside of which is a zigzagspring, 73, that presses the cartridges down in the loadingopening inthe breechcase, the cartridge which is retained in the magazine, Fig.56, by the cartridge-flange, dropping into the notches 7t one 011 eachside. The magazine has an inner leatherlining, it, in front, to preventthe points of the bullets from being damaged by the recoil during thefiring with the magazine loaded. The lower case, 7:, has acylindrically-bored rear part, 7:, in which slides carrier L, Figs. 2iand 25. The case has on one outer and lower side an eye, 7;, Fi 20, inwhich is inserted a stophook, N, Figs. 30 and 31; also a lower stud, kFig. 20, that enters the eye a. in a corresponding recess on the rightside of the breechcase, and by which the magazine is mounted. There aretwo projections, If, one on each side, inside the magazine-case. Thesesupport the flange of the cartridge when the carrier is pressing theextractor over the cartridge flange A. The tongue 7.1 at the rearextends a little under the curved plate 0 of the closingblock 0, and bythis the magazine is kept quite lirin when the mechanism is closed andready for firing. It is here also formed with a slot, 76", for thestop-pin Z of the carrier, Fig. 2i, and with a slot, If, for guiding thecarrier L at the left side. In frontit is provided with a projection,7.1, Fig. 23, that enters a slot, Z", in the front en (1 of the carrierguiding-arm 7 Fig. 2st. At the bottom, in front, there isafiange, 7: forthe point of the bullet to rest on, and

twoinnerinclincd )lanes. 7;. oneon eachside for guiding the cartridge,as shown at Figs. 23, 56, and 57. A magazine of such a size that it canhold seven cartridges appears to be the one most suitable. Having onecartridge in the barrel,eight shots will then be available. The carrierL, that moves inside the cylindrical part k in the magazine, is formedlike a cylindrical plug, Z, provided with the extractor Z, by means of wrich the cartridge is carried along so far that its. flange may pass outthrough the opening k, and the bulletpoint gets clear of the aforesaidbottom flangeseat, It. The cartridge is then free, and is pressed downin the loading-opening ol' the breech-case by the zigzag springlr, Fig.19, the fiat arm Z serving as a guide for the carrier, for which reasonit has the aforesaid slot Z for the lug It. There is a hole, Z boredaslant through the cylindrical body of the carrier, and in this turns acartridgeguard, M, Figs. 27, 2S, and 29, by the aid of which themechanism of the magazine may be put into motion or stopped at pleasure,so that the gun in that case could work as a single-loader or with abottom magazine. The carrier L receives its motion in one directionthrough the said guard M, when this is placed in such a position thatthe extractionstud 6 Fig. 12, by the backward movements of themechanism, can get hold of the catch-knob m on the magazineguard, and inthe other direction the carrier receives its motion from the roundedeffcorner a of the closing-block which incloses the mechanism, pressesagainst the end Z of the carrier, and moves it forward.

The cartridge-guard M, Fig. 27, of the magazine K consists of a smallcentral pin, m, provided with an outer ielieal spring, m, and turning inthe aforesaid oblique hole Z in the carrier by means of a catch-knob, m.The pin, when turned half round one way, comes right opposite. thelateral front lug, c, Fig. 12,-of the extractor, and in opening themechanism this lug will draw the carrier back, and thus let thecartridge in the magazine held by the carriers extractor Z, Figs. 25,56, and 57, drop down in the loading opening of the breech-case. In thereversemovement of the pin the catch-knob on will come so low that theextractors lug c" Fig. 12, will pass over it, and no motion will then becommunicated to the magazine, and firing with the gun as a single-loadermay go on without interfering with the magazine at all. The helicalspring m, together with a small stud, m, on an arm, on, for turning thepin, serves as a stopper for the two positions in which the magazine isput into motion or stopped.

The stop-hook N, Fig. 13, fixed in the eye k on the magazine K, consistsof a hook part, it a on a pin provided with a helical spring, a, whichdraws the hook part a into a notch, (6, Fig. 1, in the breech-case bywhich the loose magazine is secured.

Fig. 56 shows the position of the cartridge in the lower part of. themagazine K at the moment when the extractor Z, fixed to the cornerpressed forward by the covering-plate c, has seized the cartridgeflange.

Fig. 57 shows the position of the carrier L, with cartridge drawn backby the extractorstud 6 the cartridge here being free to pass down intothe loading-opening of the breechcase.

Figs. 58 and 59 show the gun with the magazine mounted and the mechanismclosed ready for firing.

Then the gun is also to be provided with or adapted for the magazineunder the barrel, I make such magazine in the usual tube form, as Ishall now explain with reference to Figs. 32 to 55. This tube S is madeto take eight 'cartridges,and is at one end secured in a socket, a, orthe breech-case A,(shown separately in Fig. 32,) and at the other end toa stud on the barrel. This tube-magazine also contains the usual helicalspring and runner, that press the cartridges one after the other intothe breech.

The breech-case A, Figs. 32 and 50, as adapt ed for the magazine S, isarranged as follows: A slot, a, is formedin the bottom,and in this slotworks the cartridge-feeder 0, Figs. 88, 39, and 40, which is guided by arib, 0 fitting in the inclined recess a in one side of the slot a, andis hinged to the breech-case at 0. A

screw-hole, a, on the side of the breech-case receives the stopper Q,Figs. 44, 45, for the magazine S, and there is a front recess and a rearrecess, a, for fixing the end of that stopper in its two positions. (6is a stop that limits the movements of the stopper. The eartridge-feeder0 receives the cartridge from the magazine S and receives its impulsethrough a spring, 1?, Figs. 41 and 42, and the inclined plane leading tothe hollow I) in the under side of the bolt B, Fig. 4, in the followingmanner: hen the bolt Bis drawn so far back that the lifting back end, 0of the cartridge-feeder enters the said recess, the spring P acts 011the stud 0 on the cartridgefeeder and brings the front part of the samelow enough to receive the cartridge from the magazine. It is broughtback to its former p0 sition by means of the inclined plane at therecess 5 as this plane in the forward movement of the mechanism pressesthe back end 0 of the feeder down and consequently the cartridge islifted up, as shown at Fig. 53. The cartridge that the scoop hasreceived from the magazine-tube,being forced up,is stopped against theback part of the opening a a in the breech-case. By having the aforesaidrecess b Fig. 4, in the under side of the bolt so placed, and by havinga longitudinal rib, 0, of the cartridge-feeder resting in the outerlongitudinal groove, b", in the side of the bolt, the cartridge-feeder,which in this case forms the bottom of the breech-case, is preventedfrom falling down before the empty case is ejected by the extractor E.The rib 0", as long as it is in contact with the outer groove,b, in thebolt, also relieves the lifting end of the feeder 0 from the reactingpressure caused by the extractor when in the act of ejecting the emptycartridge-case. NVhen the cartridgefeeder is down, Fig. 50, the rib 0and the inclined recess a a, Fig. 34, in the bottom of IIO thebreech-ease form a passage in which the cartridge-flange is guided, andwhereby the cartridge is prevented from getting out of the feeder beforeit reaches the extremity of the opening in the breech-case at the rearof the feeder, where the cartridge-flange at one side gets clear of therib 0, and at the same time it is released at the other side by a notch,a, in the side of the breech opening, and is then at liberty to belifted up in the breech-case by the cartridge-feeder O. The lug 0 on thefront end ofthe latter stops the cartridge in the magazinetube, the samebeing liberated by the guard t the moment the mechanism is closed, andit lies now ready to enter the cartridge-feeder when the mechanism isagain opened. The pin 0 through the lug o of the feeder serves forgiving impulse to the cartridge-guard R while closing and opening themechanism, as the pin then alternately comes in contact with the arms ofthe cartridgeguard above and below its fulcrum. There is a rib, 0",across the fore end of the scoop-formed part of the cartridge feeder,that lifts the cartridge, and thereby facilitates its entrance into thecartridge-chamber. A projection,o,prevents the cartridge flange fromfalling down behind the upper end of the cartridgefeeder when this isdown. The cartridge-feeder spring P is formed with a front stop in therear. It has also a notch, 9 by which it is fastened to the screwed luga" under the breeclrcase A. The back arms of the spring have hooks 11 bywhich it is held fast when acting on the transverse pin 0 of the arm ofthe feeder. Thus this spring presses the cartridge'feeder down when freeof the stopper Q of the repeating mechanism.

Through the pin 0 in the back end, 0, of the feeder this spring alsodepresses hook, r, of the cartridge-guard R.

The stopper Q, Figs. 43 and 44:, of the repeating mechanism consists ofa handle having at one end a screw, q, that fits into a hole, (6, Figs.33 and 34., on the left side of. the breech-case. The end of the screw qhas a short stud, q, that has one-half of its diameter filed off to aD-section, that permits it, when placed in one position, to pass throughthe slot 0 in the scoop of the cartridge-feeder, and when placed in theopposite position enters that part of the hole 0 in the scoop of thecartridge-feeder not filed out, and thus keeps the feeder up and fixed,and the gun may then be worked just as if it had no magazine S.

To keep the stopper steady in its two positions,the handle or arm q isformed as a spring, provided at the extremity with a small projection,that enters into a recess, a, in the outer side of the breech-case.

The cartridge-guard B, Fig. 46, consists of a balance-lever, the twoarms or ends 1' and r of which form an angle, and it turns on itscenter-pin 0- that works in the hole a in the magazine-tube socket a,Figs. 82, 33. The guard has a tooth, 1", that enters into a slotopening, a in the tubesocket, and hinders the cartridge that comes fromthe magazine fore end, 0', of the feeder.

from getting farther than to this claw, which is pressed into the eye inthe tube-socket a by the impulse that the feeder-spring gives to thefeeder and its stud 0 at itslowcr front end. As this latter abutsagainst the lower arm, r, of the guard and forces this down, and therebyalso the tooth into the tube-socket a this of course prevents the nextcartridge from following the one that has passed into the feeder. Thepressure of the helical magazine-spring upon the cartridge, which isstopped against the claw of the guard, keeps't-he claw in the socket,'as this pressure takes effect above the center about which the guardturns. The other impulse that the guard receives is also communicated toit through the pin 0 at the rear end of the feeder, as this pin, whenthe cartridgefeeder is lifted, pushes the upper arm, r, of the guardforward, and thus draws the guard-s claw r out of the tube-socket a, andthe cartridge resting against the claw is made free and abuts againstthe lug on the An end projection, u, Figs. 50, 52, and 53, on the barrelextends into the loading-opening of the breech-case, whereby thebullet-points, at the rapid forward movements of the mechanism, are prevented from being thrown up so high by the 9 cartridge-feeder as to abutagainst the edges of either the barrel or breech-case in theloading-opening, and thus hinder the cartridges from getting into theirplaces.

The mechanism proper of the gun is so 0011- structed that itmay also beused either for a repeating-gun with upper magazine, or for arepeating-gun with lower magazine, without removing or changing any ofthe parts of which the mechanism consists.
